What type of shape is octagon?
polygon In geometry, Octagon is a polygon that has 8 sides and 8 angles. That means the number of vertices and edges of an octagon is 8, respectively. In simple words, the octagon is an 8-sided polygon, also called 8-gon, in a two-dimensional plane. A regular octagon will have all its sides equal in length.

Is an octagon equilateral?
As demonstrated in the figure below, many possible concave octagons can be defined, with equal sides, but unequal interior angles. These octagons are called equilateral. Any octagon that is not regular is called irregular. The sum of the internal angles of any octagon, either convex or concave is always 1080°.
